New Delhi: On his maiden trip to India, Facebook co-founder and one of the world's youngest billionaires Mark Zuckerberg on Friday called on Prime Minister Narendra Modi to discuss digital expansion in the country.

Zuckerberg, who arrived in India on Thursday, met Modi on Friday evening but neither the Prime Minister's Office nor Facebook disclosed details of the meeting. Earlier in the day, he had also met Telecom and IT Minister Ravi Shankar Prasad.

Zuckerberg is the third high profile CEO of a US-based firm, after Amazon's Jeff Bezos and Microsoft's Satya Nadella, to visit India in last few days.

Yesterday, while addressing media persons, Zuckerberg had said he wanted to discuss the role Facebook can play in connecting villages and understand Modi's Digital India vision.

"One of the things I am really excited about is that the PM has this whole Digital India initiative. We can't create connectivity around the world just by ourselves, we are trying to work with operators, governments.

"I am mostly interested in hearing and learning about how we can help. I believe there are certain things that Facebookcan uniquely bring," he had said.

Stressing on the importance of connectivity, Zuckerberg had said while India has about 243 million Internet users and have 100 million plus Facebook users, there are over a billion people in the country who do not have access to the net.
